OfflineSpeechRecognition

To get a Git project into your build:

Step 1. Add the JitPack repository to your build file

gradle Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Step 2. Add the dependency

   dependencies {
     implementation 'com.github.shreyashghag:OfflineSpeechRecognition:v0.0.1'
   }

Step 3. declare the variable

lateinit var mSpeechRecognizerManager: SpeechRecognizerManager

Step 4.
check for runtime permission

  if (PermissionHandler.checkPermission(this, PermissionHandler.RECORD_AUDIO)) {
       Log.d("MainActivity:","Permission Granted")
  }
  else{
        PermissionHandler.askForPermission(PermissionHandler.RECORD_AUDIO, this)
  }

Step 5.

@BindView(R.id.result_tv)
lateinit var result_tv: TextView
@BindView(R.id.start_listen_btn)
lateinit var start_listen_btn: Button
@BindView(R.id.stop_listen_btn)
lateinit var stop_listen_btn: Button
@BindView(R.id.mute)
lateinit var mute: Button

Step 6.

setup Listensers for buttons.

start_listen_btn.setOnClickListener {
        setSpeechListener()
        result_tv.text = getString(R.string.you_may_speak)

    }
    stop_listen_btn.setOnClickListener {
        if(mSpeechManager != null) {
            result_tv.text = getString(R.string.destroied)
            mSpeechManager.destroy()
        }
    }
    mute.setOnClickListener {
        if(mSpeechManager!=null) {
            if(mSpeechManager.isInMuteMode) {
                mute.text = getString(R.string.mute)
                mSpeechManager.mute(false)
            }
            else
            {
                mute.text = getString(R.string.un_mute)
                mSpeechManager.mute(true)
            }
        }
    }

Step 7.

Initialize the mSpeechRecognizerManager in onCreate

  mSpeechManager=SpeechRecognizerManager(this,object:SpeechRecognizerManager.onResultsReady{
        override fun onResults(results: ArrayList<String>) =
            if (results != null && results.size > 0) {
                var results1=results
                Log.e("error",results.toString())
                Log.e("error",results1.toString())
                if (results1.size == 1) {
                    mSpeechManager.destroy()
                    mSpeechManager = null!!
                    //here result_tv is the textview to show the results.
                    
                    result_tv.text = results1[0]
                } else {
                    val sb = StringBuilder()
                    if (results1.size > 5) {
                        results1 = results1.subList(0, 5) as ArrayList<String>
                        Log.d("results",results1[0].toString())
                    }
                    for (result in results1) {
                        sb.append(result).append("\n")
                    }
                    result_tv.text = sb.toString()
                }
            } else result_tv.text = getString(R.string.no_results_found)
    })
